Why UnidenCommander?

Even though the UBC785XLT is a great scanner with its excellent audio quality and massive 1000 memory channels, there are some flaws in my opinion. The two greatest weaknesses of the UBC785 are the inability to change receiver modulation (AM, FM, etc.) and step size (5k, 6.25k, etc.) easily. For both option, one has to go into the settings menu to change change either value.
Luckily, UnidenCommander provides both functions as easily accessible buttons.
